In determining aluminium and sulfur in ferromolybdenum, iron and molybdenum were removed by methyl isobutyl ketone extraction method. After the removal of iron and molybdenum, aluminium was determined gravimetrically or volumetrically by using oxine, by which 0.1-1 per cent aluminium in ferromolybdenum could be determined. By using methyl isobutyl ketone for ether, the danger of explosion caused by organic vapour and the interference of molybdenum could be avoided. Sulfur was determined gravimetrically as barium sulfate down to 0.005 per cent content of it. The present procedure is superior in its simplicity and in being free of the obstruction by molybdenum trioxide to the usual combustion method for sulfur.

 

Oxine is a monoprotic bidentate chelating agent. The complexes as well as the heterocycle itself exhibit antiseptic, disinfectant, and pesticide properties, functioning as a transcription inhibitor. Its solution in alcohol is used in liquid bandages. It once was of interest as an anti-cancer drug.

 

The reaction of 8-hydroxyquinoline with aluminium(III) results in Alq3, a common component of organic light-emitting diodes (OLED's). Variations in the substituents on the quinoline rings affect its luminescence properties.

 

The roots of the invasive plant Centaurea diffusa release 8-hydroxyquinoline, which has a negative effect on plants that have not co-evolved with it.

 

Hydroxyquinoline was used as a stabilizer of hydrogen peroxide in a rocket fuel oxidizer (T-Stoff) in World War II.

 

8-Hydroxyquinoline-functionalized hydrogels devices can be utilized to build photonic nanosensors to quantify the concentrations of lead and copper. The principle of operation of these sensors is based on the chemical modulation of a hydrogel film volume that incorporates a Bragg grating. As the hydrogel swells or shrinks upon chemical stimulation, the Bragg grating changes color and diffracts light at different wavelengths. The diffracted light can be correlated with the concentration of a target analyte.
